Specification of Letters Patent;

Application filed February 10, 1906. Serial No 300.409.

Patented Jan. 15, 1907.

To all whom it may concern.-

Be it known that I, HENRY M. SoIPLE, a

' citizen ofthe United States, residing at San fication.

Francisco, in the county of San Francisco and State of California, haveinvented new and useful Improvements in Sectional Poles for Telephone,Telegra h, Trolley'Wires, and other Uses, of which t e following is aspeci- This invention relates to a sectional pole for telephone,telegraph, trolley wires, and other uses; and the same is to provide a pe of this class which is cheap in construction, strong and durable,

com aratively li ht in Wei ht, and embod P g i Y ing in its organizationin t e main material that can be readily purchased in the market,

and thus facilitating the association of the parts thereof. p

The improved sectional pole is also convenient fortransportationpurposes, as it may be shipped in sections or separateparts and.

- the pole is also extended to such an extent as to insure a betterpurchase in the ground, and thus render the complete pole more flexibleabove the ground support or anchorage, with increased strength as comared to a tubular pole and considerably lig ter than the latter.

The pole is principally made up of angleiron or bar members which areheld in connected relation by particular devices, and may be used eitherwith or without a central tie bar or rod extending therethrough.

In the drawings, embodying the preferred construction of the pole in twoforms, Fi re 1 is an elevation of a pole broken throng at several pointsand embodying the preferred features of the invention. Fig. 2 is asection on line 2 2 of Fig. 1. Fig. 3 is 'a section on line 3 3 ofFig. 1. Fig. 4 is a section on line 4 4 of Fi 1, partially broken away.Fig. 5 is an eifiarged transverse vertical section through the base orfoot of the pole. Fig. 6 is a sectional elevation of a portion of a poleembodying a modification 1n the construcprimary object of the. 0

tion. Fig. 7 is a horizontal section through the pole shown by Fig. 6.Fig. 8 is a detail of the ole illustrated by Figs. 6 and 7.

Simi ar numerals of reference refer to like parts throughout the severalviews.

The pole, as shown by Figs. 1', 2, 3, 4, and 5, is composed mainly of aseries of angle iron members 1, with the angle edges thereof disposedinwardly,-as clearly illustrated by Figs. 2, 3, and 4. Each of themembers 1 has at its lower end divergent right-angular feet 2,'which aresecured to a base-plate 3 of any suitable dimensions and adapted to bedisposed on a suitable ground-su port and anchored or secured in anysuitablb manner. Gver the feet 2 a cover-plate 4 is applied and hasangular recesses 5 at regular intervals therein to receive themembers 1. This cover-plate forms a bottom support for cement groutingor other covering material that is introduced in or applied to the ole.

members 1 coupling and-reinforce collars 5 are applied and are slightlytapered to correspond to the upward and inward inclination of themembers 1, which is preferred to reduce thepole toward its upperextremity and give the same greater stability, as will be readilyunderstood. The coupling-collar 5 may also form the coverings for jointsformed at intervals in the pole and in accordance with the length orheight of the same. The collars 5 will be of dimensions corresponding tothat portion of the pole over which they plates 6, which .serve asjoint-'septums, and also as intermediate reinforcing means against anytendency toward inward crushing strain.

with angular recesses 7 to snugly-receive the members'l, and fitting inthe members are inwardly-extending angular projections 8, formed as aart or secured to the collars or sleeves 5. n the upper ends of themembers 1 a ring'or annulus 9 is applied and is similar in constructionto the co lars 5 heretofore explained, said ring or annulus havinginwardly-extendin "angular projections 10 fitting in the mem ers 1 andalso having inside thereof a partition or septum 11, formed withrecesses 12 to receive said members. On the top of the ring or annulus 9a cap-plate 13 is secured, and this plate is intended to be 1 providedwith suitable openings for receiving are fitted, and within the same arepartitionsectional view showing the base for the form f At intervalsthroughout the length 0 the The partitions or septums 6 are each formed5 leellar or band have slots 16 formed there- 20 a base plate orsupport, and the device or de 'where a securing-nut or other means maybe?

in the form of the pole shown by 6 the main members 14: are in the formof bars se cured at their lower ends to a base 14", as

intervals collars 1 thereon. The eollars l5 operate similar to thecollars 5 and ring and said collars may be properly termed in eachinstance clampingbands.

'ihere are anumber of means of securing the lower ends of themembers it to vices which Will be found most efiectivefoii this purposeWiilbe adopted. The two forms of pole as thus far described can bemanufactured and used for any pur pose Without further strengthening, orcon necting means; but iumany instanees it is preferred that a tie-rod18 be employed there with and extend through the center thereof, thesaid tiered being secured its lower end inthe center of the base 3 andpasses upf' Wardly through openings 1?; in the partitions; 6 and 11, andalso through the cap-plate 13,;

applied thereto, as at 20,'to give additional rigidity to the pole.structure and obviate any? tendency of warping, misshaping, or disassoi,

When this rod 18 is used, it will hold the cap-plate 13 firmly in place,as Well as the members 1 and i l, it bemg understood that said rod willalso he used: with the form of the pole shown by Figs. 6: and 7,and,lurthern1ore, that a cap-plate or device similar to that shown byFig. 1 may} also be applied to the form of pole. shown by Figs. 6 and 7.E i rom the foregoing it will be observed that} the pole in either ofits forms may be readilconstructed and that the materials of whic it iscomposed may in the main be obtained. in the market, and thereby avoidthe neces sity of a special preparation, thus materially reducing thecost of manufacture and at the same time rovide a strong and durablestructure. The members assembled as exlained also provide a number ofsurfaces for eyingor holding cement filling or grouting in placetherein'or thereover, and the partitions 6, as Well as the'bottomcover-plate 4, serve as a supporting means for the filling that maybeintroduced into the pole as Well as intermediate reinforcing elementscoopersting With the rings or clamping-bands 5 and 15 to fortify thepole structure.

sens-ea and the superiority thereof o er Wooden poles and the ordinarytubular poles is manifollr. and'will be readily appreciated by thoseskilled in the art. Furthermore, it is intended to form the pole ofdifferent sizes of angle and fiat iron or bar members.

What I claim is 1. A pole of the class set forth made up of a pluralityof upwardly-extending, inwardly converging members, a base to which thelower ends of members are secured, taporing elainpingbands applied overthe said members at intervals and provided with inwardly-projectingmeans equal in number to and engaging the said members, and a capplatefitting on the upper terminals of said members, the said cap-platecovering theupper end ofthe pole and providing means for the attachmentof Wires and the like.

2. A ole of the class set forth comprising a plur ity of members formedwith angleirons with the angular portions thereof projected inwardly,said members being converged in an upward direction and separated byintervening spaces, partitions arranged Within the members and havingangular seats to receive. the inwardly-projecting angular portions ofsaid members, and tapering clams): ing-bands applied over saidmembersadja cent to and inclosing saidpartitions and provided withangular projections equsliu nu1nher to and projecting into the saidangular members.
